My big girl usually slips out of her skin in the middle of the night so we don't normally get to see it. Then usually she drops a big ole dook in it so it's straight to the dumpster. We did catch one without a giant mess in it though. Pic is about 1.5? years ago. She has put on about 2' since then.
The little guys we see shed on the regular. It's neat to watch.
